CDPK — Brachypodium distachyon

Summary

BdCDPK (BRADI_5G20082V3) on chromosome 5 of Brachypodium distachyon encodes a protein containing WD40 repeat domains and is associated with PKC binding, MAP kinase scaffold activity, translation regulator activity, structural molecule activity, and ribosome binding. The gene is linked to several biological processes including the MAPK cascade, signal transduction, cellular response to abscisic acid stimulus, seed germination, intra-Golgi and ER-to-Golgi transport, and rescue of stalled cytosolic ribosomes. It localises to the coatomer, cilium, Golgi membrane, cytosol, cytoplasm, nucleus, and ribosome. BdCDPK is associated with growth stage, and with phenotypes including drought, salt, grain size, starch biosynthesis, ABA response, and jasmonic and salicylic acid responses. Studies of related genes in other species link the family to grain yield, plant height, cold tolerance, spikelet fertility, and disease resistance.
